We axiomatize in the Anscombe-Aumann setting a wide class of preferences called rank-dependent additive preferences that includes most known models of decision under uncertainty as well as state dependent versions of these models. We prove that aggregation is possible and necessarily linear if...

This paper presents an axiomatic model of decision making under uncertainty which incorporates objective but imprecise information. Information is assumed to take the form of a probability-possibility set, that is, a set P of probability measures on the state space. The decision maker is told...

This paper concerns the difficulty of taking long-term effects on health into account in an economic valuation. Indeed, public decision makers should incorporate the cessation lag between implementation of an abatement policy and achievement of all of the expected mortality-related benefits for...
